Change in suicide rate: Model #2 OLS regression between the market risk premium (STOCK_t), the unemployment rate (UNEMP_t), the real GDP growth rate (GDP_t) and rate of change in annual suicides (Y-variable).

The overall regression F-stat is 30.69 and significant at the 0.001 p-value. The Durbin-Watson test value of 2.1038 indicates no autocorrelation in the regression residuals. The adjusted R² indicates that 74.18% of the variation in the change in suicide rate is explained by the three independent variables. Annual rates are since 1980. Data from [9], [10].
